RELATED APPLICATION

This application is an application under 35 U.S.C. 371 of InternationalApplication No. PCT/CN2017/082515 filed on Apr. 28, 2017, the entirecontents of which are incorporated herein by reference.

TECHNICAL FIELD

The disclosure relates to the technical field of communication, and moreparticularly to a channel location indication method and a relatedproduct.

BACKGROUND

5th-Generation (5G) New Radio (NR) is a subject raised recently by the3rd Generation Partnership Project (3GPP). Along with increasingly deepdiscussions about a 5G technology, on one hand, because of backwardcompatibility of a communication system, a new technology researched anddeveloped later tends to be compatible with a technology which has beenstandardized before; and on the other hand, because of existence ofnumerous existing designs for 4th Generation mobile communication (4G)Long Term Evolution (LTE), flexibility of 5G may inevitably besacrificed for compatibility to further bring reduction in performance.Therefore, researches in two directions are concurrently made by the3GPP at present. Here, the technical discussion group not consideringbackward compatibility is called 5G NR.

In an LTE system, a time-domain location of a data channel (for example,a Physical Downlink Shared Channel (PDSCH)) takes a slot and a subframeas a unit. A starting location of the PDSCH is for a slot/subframe wherethe PDSCH is located, and a serial number of a symbol where the PDSCHstarts in the subframe is indicated in a Physical Control FormatIndicator Channel (PCFICH) of the subframe. In addition, in the LTEsystem, a time-domain location of a control channel is also defined bytaking a slot/subframe as a unit, a Physical Downlink Control Channel(PDCCH) is always at a starting location of the subframe, and a PhysicalUplink Control Channel (PUCCH) occupies the whole slot/subframe.

In a 5G NR system, for improving the flexibility of data transmissionresource allocation and reducing a delay, flexibility of a time-domainlocation of a channel is greatly improved, and a symbol may be taken asa unit for allocation. All of a PDSCH, a PDCCH, a Physical Uplink SharedChannel (PUSCH) and a PUCCH may start from any symbol and take anysymbol number as a length, and it is quite difficult to configuretime-domain locations of a data channel and a control channel by takinga slot/subframe boundary as a reference point. A conventional manner ofindicating starting locations of a data channel and a control channelthrough symbol serial numbers in a slot may greatly limit theflexibility of resource allocation.

SUMMARY

Embodiments of the disclosure provide a channel location indicationmethod and a related product, to improve flexibility and efficiency ofdata channel resource allocation in a wireless communication system.

According to a first aspect, the embodiments of the disclosure provide adata transmission method, which may include the following operations.

A network-side device sends at least one piece of indicationinformation, the at least one piece of indication information beingconfigured to indicate a location offset between a data channel and afirst control channel or between a second control channel and the firstcontrol channel, the location offset including a time-domain locationoffset and/or a frequency-domain location offset and the time-domainlocation offset being a symbol-level offset.

It can be seen that, in the embodiments of the disclosure, the at leastone piece of indication information is transmitted between thenetwork-side device and a terminal, the at least one piece of indicationinformation being configured to indicate the location offset between thedata channel and the first control channel or between the second controlchannel and the first control channel. Since the location offsetincludes the time-domain location offset and/or the frequency-domainlocation offset and the time-domain location offset is a symbol-leveloffset, a time-frequency resource of the data channel or the secondcontrol channel may be conveniently determined according to the locationoffset in regardless of the symbol where the first control channel islocated respectively, namely a starting location of the resource of thechannel is not required to be indicated by a fixed subframe/slotboundary, like in an LTE system. Thus, relatively high signalingcomplexity and overhead brought by two-level indication of “indicating asubframe/slot where the channel is located and then indicating a symbolwhere the channel starts in the subframe/slot” are avoided, andimprovement in flexibility and efficiency of channel resource allocationin a wireless communication system is facilitated.

In a possible design, the at least one piece of indication informationmay include first indication information, and the first indicationinformation may be transmitted through Radio Resource Control (RRC)signaling or system information; and the first indication informationmay be configured to indicate the location offset between the datachannel and the first control channel or between the second controlchannel and the first control channel.

It can be seen that, in the example, the first indication information istransmitted between the network-side device and the terminal, and thefirst indication information may directly indicate the location offsetbetween the data channel and the first control channel or between thesecond control channel and the first control channel, so that a resourcelocation of the channel may be determined according to the locationoffset and a resource location of the first control channel, namely thestarting location of the resource of the channel is not required to beindicated by the fixed subframe/slot boundary, like in the LTE system.Thus, relatively high signaling complexity and overhead brought bytwo-level indication of “indicating the subframe/slot where the channelis located and then indicating the symbol where the channel starts inthe subframe/slot” are avoided, and improvement in the flexibility andefficiency of channel resource allocation in the wireless communicationsystem is facilitated. Since the first indication information istransmitted through RRC signaling or system information, a signalingoverhead is relatively low, data transmission efficiency of channelresource allocation is further improved, and a signaling reading delayis reduced.

In a possible design, the at least one piece of indication informationmay include second indication information, and the second indicationinformation may be transmitted through Downlink Control Information(DCI); and the second indication information may be configured toindicate the location offset between the data channel and the firstcontrol channel or between the second control channel and the firstcontrol channel.

It can be seen that, in the example, the second indication informationis transmitted between the network-side device and the terminal, and thesecond indication information may directly indicate the location offsetbetween the data channel and the first control channel or between thesecond control channel and the first control channel, so that theresource location of the channel may be determined according to thelocation offset and the resource location of the control channel, namelythe starting location of the resource of the channel is not required tobe indicated by the fixed subframe/slot boundary, like in the LTEsystem. Thus, relatively high signaling complexity and overhead broughtby two-level indication of “indicating the subframe/slot where thechannel is located and then indicating the symbol where the channelstarts in the subframe/slot” are avoided, and improvement in theflexibility and efficiency of channel resource allocation in thewireless communication system is facilitated. Since the secondindication information is transmitted through DCI, a resource of thedata channel scheduled by the control channel may be dynamicallyindicated, and the flexibility of data channel resource allocation isfurther improved.

In a possible design, the at least one piece of indication informationmay include first indication information and second indicationinformation, the first indication information may be transmitted throughRRC signaling or system information, and the second indicationinformation may be transmitted through DCI.

The first indication information may include at least one locationoffset, the second indication information may include an indicatorcorresponding to a selected location offset, the indicator may beconfigured to indicate that the location offset between the data channeland the first control channel or between the second control channel andthe first control channel is the selected location offset, and theselected location offset may be a location offset selected from the atleast one location offset.

It can be seen that, in the example, the first indication informationand the second indication information are transmitted between thenetwork-side device and the terminal and the location offset between thedata channel and the first control channel or between the second controlchannel and the first control channel is jointly indicated through thefirst indication information and the second indication information.Compared with indication by the first indication information only, thismanner may dynamically indicate the channel resource scheduled by thefirst control channel through the DCI, which improves the flexibility ofchannel resource allocation; and compared with indication by the secondindication information only, this manner limits the selected locationoffset to be values of a few location offsets through the RRC signalingor the system information, which may reduce the signaling overhead andimprove the efficiency of data channel resource allocation.

In a possible design, the at least one piece of indication informationmay include first indication information and second indicationinformation, the first indication information may be transmitted throughRRC signaling or system information, and the second indicationinformation may be transmitted through DCI.

A first location offset in the first indication information may beconfigured to indicate the location offset between the data channel andthe first control channel or between the second control channel and thefirst control channel, a second location offset in the second indicationinformation may be configured to indicate the location offset betweenthe data channel and the first control channel or between the secondcontrol channel and the first control channel, and the second locationoffset may be configured for a terminal to, responsive to detecting thatthe second location offset is different from the first location offset,determine the second location offset as the location offset between thedata channel and the first control channel or between the second controlchannel and the first control channel.

It can be seen that, in the example, the first indication informationand the second indication information are transmitted between thenetwork-side device and the terminal, the first indication informationincludes the first location offset, the second indication informationincludes the second location offset, the data channel indicated by thesecond location offset is the same as the data channel indicated by thefirst location offset, and the second location offset is configured forthe terminal to, responsive to detecting that the second location offsetis different from the first location offset, determine the secondlocation offset as the location offset between the data channel and thefirst control channel or between the second control channel and thefirst control channel, namely the second location offset may overturnthe first location offset. Compared with indication by the firstindication information only, this manner may dynamically indicate thechannel resource scheduled by the first control channel through thesecond indication information, which is favorable for improving theflexibility and accuracy of data channel resource allocation; andcompared with indication by the second indication information only, thismanner may reduce the signaling overhead and improve the efficiency ofdata channel resource allocation.

In a possible design, the at least one piece of indication informationmay include second indication information, and the second indicationinformation may be transmitted through the DCI.

The data channel or the second control channel may includetime-frequency resources in multiple frequency-domain resource elements,the second indication information may include multiple time-domainlocation offsets corresponding to the multiple frequency-domain resourceelements, and each time-domain location offset may be configured toindicate the time-domain location offset between the time-frequencyresource in the corresponding frequency-domain resource element and thefirst control channel.

It can be seen that, in the example, the second indication informationindicates different time-domain location offsets for multiplefrequency-domain resource elements to ensure that time-domain resourcesof the data channel or the second control channel in differentfrequency-domain resource elements start from different time-domainlocations, so that more flexible and efficient channel resourceallocation is implemented.

In a possible design, the at least one piece of indication informationmay include third indication information, the third indicationinformation may be configured to indicate a time-domain length of thedata channel, and the third indication information may be transmittedthrough RRC signaling and/or DCI.

It can be seen that, in the example, the at least one piece ofindication information transmitted between the network-side device andthe terminal may further include third indication information configuredto indicate the time-domain length of the data channel, so that moreflexible and efficient data channel resource allocation is implemented,and improvement in the flexibility and efficiency of data channelresource configuration in the wireless communication system isfacilitated.

It can be seen that, in the embodiments of the disclosure, the at leastone piece of indication information is transmitted between anetwork-side device and the terminal, the at least one piece ofindication information being configured to indicate the location offsetbetween the data channel and the first control channel or between thesecond control channel and the first control channel. Since the locationoffset includes the time-domain location offset and/or thefrequency-domain location offset and the time-domain location offset isa symbol-level offset, time-frequency resources of the data channel andthe second control channel may be conveniently determined according tothe location offset in regardless of the symbol where the first controlchannel is located respectively, namely a starting location of theresource of the channel is not required to be indicated by a fixedsubframe/slot boundary, like in an LTE system. Thus, relatively highsignaling complexity and overhead brought by two-level indication of“indicating a subframe/slot where the channel is located and thenindicating a symbol where the channel starts in the subframe/slot” areavoided, and improvement in flexibility and efficiency of channelresource allocation in a wireless communication system is facilitated.

The technical solutions in the embodiments of the disclosure will bedescribed below in combination with the drawings.

Referring to FIG. 1, FIG. 1 is a possible network architecture of anexemplary communication system according to an embodiment of thedisclosure. The exemplary communication system may be a 4G LTEcommunication system or a 5G NR communication system, and mayspecifically include a network-side device and a terminal. When theterminal accesses a mobile communication network provided by thenetwork-side device, the terminal forms a communication connectionconnected with the network-side device through a wireless link. Such acommunication connection may be a single-connection or a dual-connectionor a multi-connection. When the communication connection is thesingle-connection, the network-side device may be an LTE base station oran NR base station (also called a gNB). When the communication is thedual-connection (which may specifically be implemented by a CarrierAggregation (CA) technology or by multiple network-side devices) andwhen the terminal is connected with the multiple network-side devices,the multiple network-side devices include a Master Cell Group (MCG) andSecondary Cell Groups (SCGs), data is transmitted back between the cellgroups through backhauls, the MCG may be an LTE base station and theSCGs may be LTE base stations, or, the MCG may be an NR base station andthe SCGs may be LTE base stations, or, the MCG may be an NR base stationand the SCGs may be NR base stations.

In the embodiments of the disclosure, terms “network” and “system” areoften used alternately and their meanings may be understood by thoseskilled in the art. A terminal involved in the embodiments of thedisclosure may include various handheld devices, vehicle-mounteddevices, wearable devices, computing devices or other processing devicesconnected to wireless modems, which have a wireless communicationfunction, as well as User Equipment (UE), Mobile Stations (MSs),terminal devices and the like in various forms. For convenientdescription, the devices mentioned above are collectively referred to asterminals.

Referring to FIG. 2A, FIG. 2A illustrates a channel location indicationmethod according to an embodiment of the disclosure. The method includesan operation 201, specifically as follows.

In an operation 2 a 01, a network-side device sends at least one pieceof indication information, the at least one piece of indicationinformation being configured to indicate a location offset between adata channel and a first control channel, the location offset includinga time-domain location offset and/or a frequency-domain location offsetand the location offset being a symbol-level offset.

The first control channel is a channel for scheduling the data channel.

The time-domain location offset is an offset of a time-domain startinglocation and/or time-domain ending location of a time-domain resource ofthe data channel relative to a time-domain starting location and/ortime-domain ending location of a time-domain resource of the firstcontrol channel; or, the time-domain location offset is an offset of atime-domain starting location and/or ending location of a time-frequencyresource of the data channel relative to a time-domain starting locationand/or time-domain ending location of a preset time-frequency resource,the preset time-frequency resource including a resource set or searchspace of the first control channel.

The frequency-domain location offset is an offset of a frequency-domainstarting location and/or frequency-domain ending location of afrequency-domain resource of the data channel relative to afrequency-domain starting location and/or frequency-domain endinglocation of a frequency-domain resource of the first control channel.

A unit of the time-domain location offset may be a symbol-level unit,for example, 1 symbol, 2 symbols or more symbols. On such a basis, aunit of the time-domain location offset may also be a combination of asymbol and a slot, a combination of a symbol and a mini-slot, and thelike. A unit of the frequency-domain location offset may be any one of:a resource block and a preset number of resource blocks.

In an operation 2 a 02, a terminal receives the at least one piece ofindication information, the at least one piece of indication informationbeing configured to indicate the location offset between the datachannel and the first control channel, the location offset including thetime-domain location offset and/or the frequency-domain location offsetand the location offset being a symbol-level offset.

In an operation 2 a 03, the terminal determines the location offset ofthe data channel relative to the first control channel according to theat least one piece of indication information.

In an operation 2 a 04, the terminal determines a location of the datachannel scheduled by the first control channel according to the locationoffset of the data channel relative to the first control channel and alocation of the first control channel.

The location of the data channel may be a location of the time-frequencyresource of the data channel.

In an operation 2 a 05, the terminal transmits first data over the datachannel scheduled by the control channel.

In an operation 2 a 06, the network-side device receives first data overthe data channel scheduled by the control channel.

It can be seen that, in the embodiment of the disclosure, at least onepiece of indication information is transmitted between a network-sidedevice and a terminal, the at least one piece of indication informationbeing configured to indicate the location offset between a data channeland a first control channel. The location offset includes a time-domainlocation offset and/or a frequency-domain location offset and thetime-domain location offset is a symbol-level offset, therefore, thetime-frequency resource of the data channel may be convenientlydetermined according to the location offset in regardless of the symbolwhere the first control channel is located, namely, a starting locationof the resource of the data channel is not required to be indicated by afixed subframe/slot boundary, like in an LTE system. Thus, relativelyhigh signaling complexity and overhead brought by two-level indicationof “indicating a subframe/slot where the channel is located and thenindicating a symbol where the channel starts in the subframe/slot” areavoided, and improvement in flexibility and efficiency of data channelresource allocation in a wireless communication system is facilitated.

Similar to FIG. 2A, referring to FIG. 2B, FIG. 2B illustrates a channellocation indication method according to an embodiment of the disclosure.The method includes an operation 2 b 01, specifically as follows.

In the operation 2 b 01, a network-side device sends at least one pieceof indication information, the at least one piece of indicationinformation being configured to indicate a location offset between asecond control channel and a first control channel, the location offsetincluding a time-domain location offset and/or a frequency-domainlocation offset and the location offset being a symbol-level offset.

The first control channel is a channel for scheduling a data channel.

The time-domain location offset is an offset of a time-domain startinglocation and/or time-domain ending location of a time-domain resource ofthe second control channel relative to a time-domain starting locationand/or time-domain ending location of a time-domain resource of thefirst control channel; or, the time-domain location offset is an offsetof a time-domain starting location and/or ending location of atime-frequency resource of the second control channel relative to atime-domain starting location and/or time-domain ending location of apreset time-frequency resource, the preset time-frequency resourceincluding a resource set or search space of the first control channel.

The frequency-domain location offset is an offset of a frequency-domainstarting location and/or frequency-domain ending location of afrequency-domain resource of the second control channel relative to afrequency-domain starting location and/or frequency-domain endinglocation of a frequency-domain resource of the first control channel.

In an operation 2 b 02, a terminal receives the at least one piece ofindication information, the at least one piece of indication informationbeing configured to indicate the location offset between the secondcontrol channel and the first control channel, the location offsetincluding the time-domain location offset and/or the frequency-domainlocation offset and the location offset being a symbol-level offset.

In an operation 2 b 03, the terminal determines the location offset ofthe second control channel relative to the first control channelaccording to the at least one piece of indication information.

In an operation 2 b 04, the terminal determines a location of the secondcontrol channel according to the location offset of the second controlchannel relative to the first control channel and a location of thefirst control channel.

The location of the second control channel may be a location of thetime-frequency resource of the second control channel.

In an operation 2 b 05, the terminal transmits second data over thesecond control channel.

In 2 b 06, the network-side device receives the second data over thesecond control channel.

It can be seen that, in the embodiment of the disclosure, at least onepiece of indication information is transmitted between a network-sidedevice and a terminal, the at least one piece of indication informationbeing configured to indicate the location offset between the secondcontrol channel and the first control channel. Since the location offsetincludes a time-domain location offset and/or a frequency-domainlocation offset and the time-domain location offset is a symbol-leveloffset, the time-frequency resource of the second control channel may beconveniently determined according to the location offset in regardlessof the symbol where the first control channel is located, namely, astarting location of the resource of the second control channel is notrequired to be indicated by a fixed subframe/slot boundary, like in anLTE system. Thus, relatively high signaling complexity and overheadbrought by two-level indication of “indicating a subframe/slot where thechannel is located and then indicating a symbol where the channel startsin the subframe/slot” are avoided, and improvement in flexibility andefficiency of control channel resource allocation in a wirelesscommunication system is facilitated.

In a possible example, the at least one piece of indication informationincludes first indication information, and the first indicationinformation is transmitted through RRC signaling or system information;and the first indication information is configured to indicate thelocation offset between the data channel and the first control channelor between the second control channel and the first control channel.

It can be seen that, in the example, the first indication information istransmitted between the network-side device and the terminal, and thefirst indication information may directly indicate the location offsetbetween the data channel and the first control channel or between thesecond control channel and the first control channel, so that a resourcelocation of the channel may be determined according to the locationoffset, and a resource location of the first control channel, namely thestarting location of the resource of the channel, is not required to beindicated by the fixed subframe/slot boundary, like in an LTE system.Thus, relatively high signaling complexity and overhead brought bytwo-level indication of “indicating the subframe/slot where the channelis located and then indicating the symbol where the channel starts inthe subframe/slot” are avoided, and improvement in the flexibility andefficiency of channel resource allocation in a wireless communicationsystem is facilitated. Since the first indication information istransmitted through RRC signaling or system information, a signalingoverhead is relatively low, data transmission efficiency of channelresource allocation is further improved, and a signaling reading delayis reduced.

In a possible example, the at least one piece of indication informationincludes second indication information, and the second indicationinformation is transmitted through downlink control information (DCI);and the second indication information is configured to indicate thelocation offset between the data channel and the first control channelor between the second control channel and the first control channel.

It can be seen that, in the example, the second indication informationis transmitted between the network-side device and the terminal, and thesecond indication information may directly indicate the location offsetbetween the data channel and the first control channel or between thesecond control channel and the first control channel, so that theresource location of the channel may be determined according to thelocation offset, and the resource location of the control channel,namely the starting location of the resource of the channel, is notrequired to be indicated by the fixed subframe/slot boundary, like in anLTE system. Thus, relatively high signaling complexity and overheadbrought by two-level indication of “indicating the subframe/slot wherethe channel is located and then indicating the symbol where the channelstarts in the subframe/slot” are avoided, and improvement in theflexibility and efficiency of channel resource allocation in thewireless communication system is facilitated. Since the secondindication information is transmitted through DCI, a resource of thedata channel scheduled by the control channel may be dynamicallyindicated, and the data flexibility of channel resource allocation isfurther improved.

In a possible example, the at least one piece of indication informationincludes first indication information and second indication information,the first indication information is transmitted through RRC signaling orsystem information, and the second indication information is transmittedthrough DCI.

The first indication information includes at least one location offset,the second indication information includes an indicator corresponding toa selected location offset, the indicator is configured to indicate thatthe location offset between the data channel and the first controlchannel or between the second control channel and the first controlchannel is the selected location offset, and the selected locationoffset is a location offset selected from the at least one locationoffset.

It can be seen that, in the possible example, the first indicationinformation and the second indication information are transmittedbetween the network-side device and the terminal and the location offsetbetween the data channel and the first control channel or between thesecond control channel and the first control channel is jointlyindicated through the first indication information and the secondindication information. Compared with indication by the first indicationinformation only, this manner may dynamically indicate the channelresource scheduled by the first control channel through DCI, whichimproves the flexibility of channel resource allocation; and comparedwith indication by the second indication information only, this mannerlimits the selected location offset to be values of a few locationoffsets through RRC signaling or system information, which may reducethe signaling overhead and improve the efficiency of data channelresource allocation.

In the abovementioned possible example, the at least one piece ofindication information includes the first indication information and thesecond indication information, the first indication information istransmitted through RRC signaling or system information, and the secondindication information is transmitted through DCI.

A first location offset in the first indication information isconfigured to indicate the location offset between the data channel andthe first control channel or between the second control channel and thefirst control channel, a second location offset in the second indicationinformation is configured to indicate the location offset between thedata channel and the first control channel or between the second controlchannel and the first control channel, and the second location offset isconfigured for the terminal to, responsive to detecting that the secondlocation offset is different from the first location offset, determinethe second location offset as the location offset between the datachannel and the first control channel or between the second controlchannel and the first control channel.

It can be seen that, in the example, the first indication informationand the second indication information are transmitted between thenetwork-side device and the terminal, the first indication informationincludes the first location offset, the second indication informationincludes the second location offset, the data channel indicated by thesecond location offset is the same as the data channel indicated by thefirst location offset, and the second location offset is configured forthe terminal to, responsive to detecting that the second location offsetis different from the first location offset, determine the secondlocation offset as the location offset between the data channel and thefirst control channel or between the second control channel and thefirst control channel, namely the second location offset may overturnthe first location offset. Compared with indication by the firstindication information only, this manner may dynamically indicate thechannel resource scheduled by the first control channel through thesecond indication information, which is favorable for improving the dataflexibility and accuracy of channel resource allocation; and comparedwith indication by the second indication information only, this mannermay reduce the signaling overhead and improve the efficiency of datachannel resource allocation.

In a possible example, the at least one piece of indication informationincludes second indication information, and the second indicationinformation is transmitted through DCI.

The data channel includes time-domain resources in multiplefrequency-domain resource elements, the second indication informationincludes multiple time-domain location offsets corresponding to themultiple frequency-domain resource elements, and each time-domainlocation offset is configured to indicate the time-domain locationoffset between the time-domain resource in the correspondingfrequency-domain resource element and the first control channel.

It can be seen that, in the example, the second indication informationindicates different time-domain location offsets for multiplefrequency-domain resource elements to support the time-domain resourcesof the data channel or the second control channel in differentfrequency-domain resource elements to start from different time-domainlocations, so that more flexible and efficient data channel resourceallocation is implemented.

In a possible example, the at least one piece of indication informationincludes first indication information and second indication information,the first indication information is transmitted through RRC signaling orsystem information, and the second indication information is transmittedthrough DCI.

The data channel or the second control channel includes time-domainresources in multiple frequency-domain resource elements, the firstindication information includes at least one time-domain locationoffset, the second indication information includes multiple indicatorscorresponding to the multiple frequency-domain resource elements, themultiple indicators further correspond to multiple time-domain locationoffsets selected from the at least one time-domain location offset, andeach indicator in the multiple indicators is configured to indicate thatthe location offset between the data channel in the correspondingfrequency-domain resource element and the first control channel is thetime-domain location offset corresponding to the indicator.

In a possible example, the at least one piece of indication informationfurther includes a default location offset, and the default locationoffset is configured for the terminal, when not obtaining the locationoffset between the data channel and the first control channel or betweenthe second control channel and the first control channel from the firstindication information and the second indication information, todetermine the location offset between the data channel and the firstcontrol channel or between the second control channel and the firstcontrol channel.

It can be seen that, in the example, for the data channel or secondcontrol channel of which the time-domain location offset is notexplicitly indicated by the first indication information and the secondindication information, the time-domain location offset of the datachannel or the second control channel relative to the first controlchannel may be determined through a default time-domain location offset,so that the condition that a time-domain location of the data channelmay not be determined in the case of false detection and missing ofrelated control signaling is avoided, and improvement in reliability ofchannel resource allocation in the wireless communication system isfacilitated.

In a possible example, the at least one piece of indication informationfurther includes third indication information, the third indicationinformation is configured to indicate a time-domain length of the datachannel, and the third indication information is transmitted through RRCsignaling and/or DCI.

It can be seen that, in the example, the at least one piece ofindication information transmitted between the network-side device andthe terminal may further include the third indication informationconfigured to indicate the time-domain length of the data channel, sothat more flexible and efficient data channel resource allocation isimplemented, and improvement in the flexibility and efficiency of datachannel resource configuration in the wireless communication system isfacilitated.

Compared with indication by RRC signaling, indicating thetime-domain location offset between the PDSCH and the PDCCH through thePDCCH may dynamically indicate a resource of the scheduled PDSCH.Therefore, more flexible data channel resource allocation may beimplemented. However, compared with indication by RRC signaling, thismanner is relatively high in signaling overhead.

The offset may take a symbol,several symbols, a symbol and a slot, and a symbol and a mini-slot as aunit. Compared with indication by RRC signaling, indicating atime-domain location offset between a PUCCH and a PDSCH through a PDCCHmay dynamically indicate a resource of the corresponding PUCCH (forexample, a PUCCH for transmitting an ACK/NACK corresponding to thePDSCH).

FIG. 3P is a schematic diagram of indicatinga time-domain location offset of a PUCCH relative to a PDCCH through thePDCCH according to an embodiment of the disclosure. As shown in thefigure, in the embodiment, the time-domain location offset of a PUCCHrelative to a PDCCH is indicated through the PDCCH. The offset may takea symbol, several symbols, a symbol and a slot, and a symbol and amini-slot as a unit. Compared with indication by RRC signaling,indicating the time-domain location offset between a PUCCH and a PDCCHthrough the PDCCH may dynamically indicate a resource of the PUCCH.Therefore, more flexible control channel resource allocation may beimplemented.

Consistent with the embodiments shown in FIG. 2A and FIG. 2B, referringto FIG. 4, FIG. 4 is a structure diagram of a network-side deviceaccording to an embodiment of the disclosure. As shown in the figure,the network-side device includes one or more processors, a memory, atransceiver and one or more programs. The one or more programs arestored in the memory and are configured to be executed by the one ormore processors. The programs include instructions configured to executethe following step.

At least one piece of indication information is sent, the at least onepiece of indication information being configured to indicate a locationoffset between a data channel and a first control channel or between asecond control channel and the first control channel, the locationoffset including a time-domain location offset and/or a frequency-domainlocation offset and the time-domain location offset being a symbol-leveloffset.

It can be seen that, in the embodiment of the disclosure, at least onepiece of indication information is transmitted between a network-sidedevice and a terminal, the at least one piece of indication informationbeing configured to indicate a location offset between a data channeland a first control channel or between a second control channel and thefirst control channel. Since the location offset includes a time-domainlocation offset and/or a frequency-domain location offset and thetime-domain location offset is a symbol-level offset, a time-frequencyresource of the data channel or the second control channel may beconveniently determined according to the location offset in regardlessof a symbol where the first control channel is located respectively,namely a starting location of the resource of the channel is notrequired to be indicated by a fixed subframe/slot boundary, like in anLTE system. Therefore, relatively high signaling complexity and overheadbrought by two-level indication of “indicating a subframe/slot where thechannel is located and then indicating a symbol where the channel startsin the subframe/slot” are avoided, and improvement in flexibility andefficiency of channel resource allocation in a wireless communicationsystem is facilitated.

In a possible example, the at least one piece of indication informationincludes first indication information, and the first indicationinformation is transmitted through RRC signaling or system information;and the first indication information is configured to indicate thelocation offset between the data channel and the first control channelor between the second control channel and the first control channel.

It can be seen that, in the example, the first indication information istransmitted between the network-side device and the terminal, and thefirst indication information may directly indicate the location offsetbetween the data channel and the first control channel or between thesecond control channel and the first control channel, so that a resourcelocation of the channel may be determined according to the locationoffset and a resource location of the first control channel, namely thestarting location of the resource of the channel is not required to beindicated by the fixed subframe/slot boundary, like in an LTE system.Thus, relatively high signaling complexity and overhead brought bytwo-level indication of “indicating the subframe/slot where the channelis located and then indicating the symbol where the channel starts inthe subframe/slot” are avoided, and improvement in the flexibility andefficiency of channel resource allocation in a wireless communicationsystem is facilitated. Since the first indication information istransmitted through RRC signaling or system information, a signalingoverhead is relatively low, data transmission efficiency of channelresource allocation is further improved, and a signaling reading delayis reduced.

In a possible example, the at least one piece of indication informationincludes second indication information, and the second indicationinformation is transmitted through DCI; and the second indicationinformation is configured to indicate the location offset of the datachannel relative to the control channel.

It can be seen that, in the example, the second indication informationis transmitted between the network-side device and the terminal, and thesecond indication information may directly indicate the location offsetbetween the data channel and the first control channel or between thesecond control channel and the first control channel, so that theresource location of the channel may be determined according to thelocation offset and the resource location of the control channel, namelythe starting location of the resource of the channel is not required tobe indicated by the fixed subframe/slot boundary, like in the LTEsystem. Thus, relatively high signaling complexity and overhead broughtby two-level indication of “indicating the subframe/slot where thechannel is located and then indicating the symbol where the channelstarts in the subframe/slot” are avoided, and improvement in theflexibility and efficiency of channel resource allocation in a wirelesscommunication system is facilitated. Since the second indicationinformation is transmitted through DCI, a resource of the data channelscheduled by the control channel may be dynamically indicated, and thedata flexibility of channel resource allocation is further improved.

In a possible example, the at least one piece of indication informationincludes first indication information and second indication information,the first indication information is transmitted through RRC signaling orsystem information, and the second indication information is transmittedthrough DCI.

The first indication information includes at least one location offset,the second indication information includes an indicator corresponding toa selected location offset, the indicator is configured to indicate thatthe location offset between the data channel and the first controlchannel or between the second control channel and the first controlchannel is a selected location offset, and the selected location offsetis a location offset selected from the at least one location offset.

It can be seen that, in the example, the first indication informationand the second indication information are transmitted between thenetwork-side device and the terminal, and the location offset betweenthe data channel and the first control channel or between the secondcontrol channel and the first control channel is jointly indicatedthrough the first indication information and the second indicationinformation. Compared with indication by the first indicationinformation only, this manner may dynamically indicate the channelresource scheduled by the first control channel through DCI, whichimproves the flexibility of channel resource allocation; and comparedwith indication by the second indication information only, this mannerlimits the selected location offset to be values of a few locationoffsets through RRC signaling or system information, which may reducethe signaling overhead and improve the efficiency of data channelresource allocation.

In a possible example, the at least one piece of indication informationincludes first indication information and second indication information,the first indication information is transmitted through RRC signaling orthe system information, and the second indication information istransmitted through DCI.

A first location offset in the first indication information isconfigured to indicate the location offset between the data channel andthe first control channel or between the second control channel and thefirst control channel, a second location offset in the second indicationinformation is configured to indicate the location offset between thedata channel and the first control channel or between the second controlchannel and the first control channel, and the second location offset isconfigured for the terminal to, responsive to detecting that the secondlocation offset is different from the first location offset, determinethe second location offset as the location offset between the datachannel and the first control channel or between the second controlchannel and the first control channel.

It can be seen that, in the example, the first indication informationand the second indication information are transmitted between thenetwork-side device and the terminal, the first indication informationincludes the first location offset, the second indication informationincludes the second location offset, the data channel indicated by thesecond location offset is the same as the data channel indicated by thefirst location offset, and the second location offset is configured forthe terminal to, responsive to detecting that the second location offsetis different from the first location offset, determine the secondlocation offset as the location offset between the data channel and thefirst control channel or between the second control channel and thefirst control channel, namely the second location offset may overturnthe first location offset. Compared with indication by the firstindication information only, this manner may dynamically indicate thechannel resource scheduled by the first control channel through thesecond indication information, which is favorable for improving theflexibility of and accuracy data channel resource allocation; andcompared with indication by the second indication information only, thismanner may reduce the signaling overhead and improve the efficiency ofdata channel resource allocation.

In a possible example, the at least one piece of indication informationincludes second indication information, and the second indicationinformation is transmitted through DCI.

The data channel or the second control channel includes time-frequencyresources in multiple frequency-domain resource elements, the secondindication information includes multiple time-domain location offsetscorresponding to the multiple frequency-domain resource elements, andeach time-domain location offset is configured to indicate thetime-domain location offset between the time-frequency resource in thecorresponding frequency-domain resource element and the control channel.

It can be seen that, in the example, the second indication informationindicates different time-domain location offsets for multiplefrequency-domain resource elements to ensure that time-domain resourcesof the data channel or the second control channel in differentfrequency-domain resource elements start from different time-domainlocations, so that more flexible and efficient channel resourceallocation is implemented.

In a possible example, the at least one piece of indication informationincludes third indication information, the third indication informationis configured to indicate a time-domain length of the data channel, andthe third indication information is transmitted through RRC signalingand/or DCI.

It can be seen that, in the example, the at least one piece ofindication information transmitted between the network-side device andthe terminal may further include third indication information configuredto indicate the time-domain length of the data channel, so that moreflexible and efficient data channel resource allocation is implemented,and improvement in the flexibility and efficiency of data channelresource configuration of the wireless communication system isfacilitated.

It can be seen that, in the embodiment of the disclosure, the at leastone piece of indication information is transmitted between anetwork-side device and a terminal, the at least one piece of indicationinformation being configured to indicate a location offset between adata channel and a first control channel or between a second controlchannel and the first control channel. Since a location offset includesa time-domain location offset and/or a frequency-domain location offsetand the time-domain location offset is a symbol-level offset, atime-frequency resource of the data channel or the second controlchannel may be conveniently determined according to the location offsetin regardless of a symbol where the first control channel is locatedrespectively, namely a starting location of the resource of the channelis not required to be indicated by a fixed subframe/slot boundary, likein an LTE system. Thus, relatively high signaling complexity andoverhead brought by two-level indication of “indicating a subframe/slotwhere the channel is located and then indicating a symbol where thechannel starts in the subframe/slot” are avoided, and improvement inflexibility and efficiency of channel resource allocation in a wirelesscommunication system is facilitated.

In a possible example, the at least one piece of indication informationincludes first indication information, and the first indicationinformation is transmitted through RRC signaling or system information;and the first indication information is configured to indicate thelocation offset between the data channel and the first control channelor between the second control channel and the first control channel. Ina possible example, the at least one piece of indication informationincludes second indication information, and the second indicationinformation is transmitted through DCI; and the second indicationinformation is configured to indicate the location offset between thedata channel and the first control channel or between the second controlchannel and the first control channel.

The first indication information includes at least one location offset,the second indication information includes an indicator corresponding toa selected location offset, the indicator is configured to indicate thatthe location offset of the data channel relative to the control channelis the selected location offset, and the selected location offset is alocation offset selected from the at least one location offset.

In a possible example, the at least one piece of indication informationincludes the first indication information and the second indicationinformation, the first indication information is transmitted through RRCsignaling or system information, and the second indication informationis transmitted through DCI.

A first location offset in the first indication information isconfigured to indicate the location offset between the data channel andthe first control channel or between the second control channel and thefirst control channel, a second location offset in the second indicationinformation is configured to indicate the location offset between thedata channel and the first control channel or between the second controlchannel and the first control channel, and the second location offset isconfigured for the terminal to, responsive to detecting that the secondlocation offset is different from the first location offset, determinethe second location offset as the location offset between the datachannel and the first control channel or between the second controlchannel and the first control channel.
